Seal glands for butterfly valves

A butterfly valve includes a valve body 102 and a valve retainer 108 mounted to the valve body. The valve body 102 and the valve retainer 108 define a circumferential cavity 302 that includes first 306 and second 308 surfaces substantially perpendicular to a longitudinal axis of a flow path of proce...

description A butterfly valve includes a valve body 102 and a valve retainer 108 mounted to the valve body. The valve body 102 and the valve retainer 108 define a circumferential cavity 302 that includes first 306 and second 308 surfaces substantially perpendicular to a longitudinal axis of a flow path of process fluid through the butterfly valve. The second surface 308 is offset from the first surface 306. A third surface 310 extends between the first surface 306 and the second surface 308. The first surface 306, second surface 308, and third surface 310 enable a seal 320 to translate within the cavity 302 in a direction substantially parallel to the first surface 306.
